Its just too disproportional from the rear. The GT3 has a wide body kit thats why it looks good on it. If it was a bit smaller and lower and with more discreet mounting brackets it would look more elegant in my opinion... Something like this:

its tough...the reactions are mixed..some really like it..some really hate it..I will be tracking it..but also wanna make sure the car still looks somewhat classy..kinda like a lot of exotics also have gt wings..but still manages to be aggressive exotic..feel like the z4 is too pretty..needs to roughen up a bit.

nicknaz: i can adjust the width of he post. in fact, i like center mounting more just because it keeps the slim long lines of the z4..but might experiment with the width regardless. as for height its adjustable up or down about an inch. but for a wing to be useful it has to match the line of the roof or come close to it.

Moo: 20" wheels are for street..will pick up a pair of wheels jus for track and swap on track days and stuff
